Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid metering device used for rinsing a dishwasher or the like.

2. Description of the Related Art Conventionally, there is known a liquid measuring device for charging a rinsing liquid in a dishwasher as shown in FIG. Case
20 accommodates the liquid 21 and rotates in a vertical state and a horizontal state. Then, as shown in FIG. 3B, when the liquid 21 falls down in the direction of the arrow e (when the case 20 is horizontal), the liquid 21 to be measured is collected in the direction of the arrow A due to the gradient of the inner wall of the case 20, and the partition wall is formed. Gather near 22. Next, in this state
When 20 is set in the direction of arrow a (when the case 13 is set upright), the liquid collected near the partition wall 22 flows into the measuring chamber 23, and excess liquid flows down in the direction of arrow B to drop a certain amount of liquid. Is to be weighed.

Problems to be Solved by the Invention In the above-described measuring device, when the amount of the liquid 21 to be measured decreases, the liquid level of the liquid 21 collected near the partition wall 22 decreases, and even when the case 20 is in the vertical state, the measurement is performed. Room 23 cannot be filled. Therefore, there is a problem that the measurement becomes inaccurate when the liquid 21 is reduced to some extent.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a liquid measuring device capable of measuring as accurately as possible even if the liquid is reduced to some extent.

Means for Solving the Problems In order to achieve the above object, a liquid measuring device of the present invention includes a case that accommodates a liquid and rotates between a vertical state and a horizontal state, and a case that is provided inside the case, and the case has a horizontal state. Sometimes, the liquid is supplied by the inclination of the case, the measuring chamber is provided inside the case to overflow the liquid supplied in the vertical state and weighs a certain amount, and the measuring chamber is provided in the vertical state of the liquid supplied when the case is in the horizontal state. And a partition wall for guiding to

Operation With the above configuration, even if the liquid in the case is reduced to some extent, if the case is made vertical, the liquid is guided to the partition wall and guided to the measuring chamber, where it is accurately measured. is there.

An embodiment of the present invention will be described below with reference to the accompanying drawings.
1 and 2, reference numeral 1 denotes a case that accommodates a liquid 2 and rotates between a vertical state and a horizontal state. Reference numeral 3 denotes a case provided inside the case 1, and liquid is supplied by an inclined wall 4 of the case when the case is in a horizontal state. A measuring chamber for overflowing the liquid supplied in the vertical state and measuring it to a constant amount, 5 is a partition wall constituting the measuring chamber 3, 6 is provided inside the case, and the liquid supplied in the horizontal state of the case is vertically It is a partition wall which guides to the measuring chamber 5 in the state. As shown in FIG. 1, the partition wall 6 is provided to be inclined, and its lower side faces the measuring chamber 3 with an overflow channel 7, and its upper side faces the inner wall of the case 1 and the inflow path 8. Is provided. 9 is a discharge valve for discharging the liquid 2 in the measuring chamber 3 out of the case, 10 is a discharge hole, 11 is a liquid supply port of the case 1, 12 is its cap, 13 is a support base of the case 1, 14 is its rotating shaft, Reference numeral 15 denotes a pit surrounded by the case 1 and the partition wall 6.

In the above configuration, the solid line state in the figure indicates the vertical state of the case 1 and the state in which the reduced liquid 2 is stored in the lower part of the case 1. When the case 3 is rotated in the direction of arrow b, the liquid 2 flows in the direction of arrow C, and flows into the pit 15 from the inflow path 8. Next, when the case 1 is rotated in the direction of the arrow a, the liquid 2 flowing on the partition wall 6 is collected by the partition wall 6 in the direction of the arrow D and poured into the measuring chamber 3.

At this time, part of the liquid 2 flows down in the direction of arrow E, but most of the liquid 2 once flowing into the pit 15
The liquid 2 can be more accurately measured when the amount of the liquid 2 becomes small.

In the above-described embodiment, the liquid measuring device itself is shown. However, in actuality, the case 1 is incorporated in a dishwasher door,
The liquid can be automatically measured when the door is opened and closed. In this case, the liquid can be a rinsing liquid.

Advantageous Effects of the Invention As is apparent from the above-described embodiment, the simple configuration of providing the partition wall in the case enables more accurate measurement than the conventional method even when the remaining amount of the liquid is small.
